Reserve is part of the diagnosis
A watch that will run on a full wind but fails to maintain power on the wrist may point toward winding efficiency rather than only escapement regulation.
Noise needs context
Some rotor sound is normal. New grinding, scraping, looseness or dramatic change is not something to ignore.
The winding system is not isolated
A tired mainspring, movement friction or other condition can reduce useful reserve even if the automatic mechanism itself is functioning.
Measure what you can
Tell us approximately how long the watch runs after being fully wound or worn and whether that behavior changed suddenly.
How the mail-in process works
Submit the watch details and photos first. If the repair appears appropriate, we provide current shipping instructions. Final scope and price follow physical inspection, and billable repair work begins only after authorization under the service terms.
